SUMMARY OF THE INVENTION

[0012] The present invention cleaning brush includes a handle member and a brush member which are connected to one another in a locking/unlocking fashion and wherein they are separated from one another by a mechanism component that is located on the handle member remotely from the brush member. The handle member has a first end and a second end, with the first end having a handle portion and the second end having means for removably attaching the brush member. The brush member is removably attached to the second end of the handle member. The brush member has one of a male and female fittage and the second end of the handle member has the other of the male fittage and said female fittage so the one slides into the other. There is a locking mechanism for locking and unlocking the male fittage and the female fittage relative to one another. The locking mechanism includes lock-unlock manually operated component remotely located from the brush member, typically toward or near the first end of the handle member. The handle member may include a gripping area adjacent to its first end.

[0013] In some present invention cleaning brush embodiments, the handle member is at least partially hollow and the locking mechanism is contained within the hollow area.

[0014] In one preferred embodiment, the cleaning brush handle member is at least partially hollow and includes at least two slits beginning at the second end and extending towards the first end so as to create at least two flexible sections. These at least two flexible sections each contain one of a protrusion or a recess, and the brush member contains the other of the protrusion and the recess such that, in a rest position, the brush member is connected to the handle member at the male and the female fittages with the protrusions interlocking with the recesses, and, in a non-rest position, wherein when a user squeezes the at least two flexible sections, the protrusions are removed from the recesses so as to unlock said brush member from the handle member.

[0015] In other present invention embodiments, the cleaning brush handle member is at least partially hollow and the locking mechanism includes a lock-unlock latch adjacent the second end of the handle member and a lock-unlock manually operated component connected thereto. The manually operated component is remotely located from the second end, and the lock-unlock manually operated component is selected from the group consisting of a button, a switch, a knob, a trigger, a dial, and a pull.

[0016] In some embodiments, the brush member may be made of biodegradable material. It may be a flat or rounded structure, with a pod, a sponge, bristles, or any other scrubbing or cleaning adaptation.

[0017] In many preferred embodiments of the present invention cleaning brush, the handle member has the male fittage and the brush member has female fittage, so that the handle member slides into the brush member. Further, although a circular cross-section for the fittages is typical for the present invention cleaning brush, the cross-sections could be of any choice, e.g. square, rectangular, oval, hexagonal, irregular, etc, as long as they fit into on another.

[0018] In some embodiments, the cleaning brush handle member contains the recesses and the brush member contains the protrusions which extend outwardly therefrom and are adapted to fit into the recesses. In other embodiments, the opposite arrangement may be employed. The recesses may be orifices or indentations, and orifices are preferred.

[0019] In the present invention preferred embodiments, the handle member has a first end and a second end, and the handle member has two halves, a first half extending from a midpoint to the first end and a second half extending from that midpoint to the second end. The first end has a handle portion, i.e. an area that is adapted to be hand held, and the second end has means for removably attaching the brush member. This foregoing establishes more specifically that, in preferred embodiments, the operating component of the lock-unlock mechanism is not only remotely located, but is located in the upper half of the handle member.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0027]FIG. 1 shows one preferred embodiment of a present invention cleaning brush 1. In this top view there is a handle member 3 adapted for connection to a brush member 31. Handle member 3 has a first end 5 and a second end 7. There is a midpoint 9 and above it to first end 5 which forms a handle portion formed of first section 11 which is inherently adapted to the handheld by its elongated shape and size. It could be cross sectionally round, square, hexagonal, rectangular, or otherwise, or could even have an irregular shape. Below midpoint 9 down to second end 7 is second half 13 adapted for and including means for removably attaching brush member 31. Second half 13 has protrusions 23 and 25 as shown and, because of cutout areas 27 and 29, segments 10 and 20 will, in a spring like fashion, close together when squeezed so as to permit the male fittage formed at second end 7 to be inserted into female fittage 33 of brush member 31. This is done by squeezing handle member 3 at areas 15 and 17 or 19 and 21. Upon insertion and release, protrusions 23 and 25 will pop into recesses 37 and 39 of female fittage 33 to secure brush 31 in a locked fashion to handle member 3.

[0028] Pad 35 of the brush member 31 is utilized to clean, for example, sanitary facilities such as toilet bowls and bidets. Thereafter, the brush member 31 may be disposed of simply by squeezing the handle member 3 to cause inserts 23 and 25 to pull inwardly away from recesses 37 and 39 so that brush member 31 drops away. Thus, a user need not touch the wet or contaminated portions of the handle member 3 or the brush member 31.

[0029]FIG. 2 shows a partial top view of an alternative embodiment present invention cleaning brush 51. It is similar to that shown in FIG. 1 . However, this version has reversed the protrusions and recesses, and, additionally, relies upon an internal living spring in the handle member.

[0030] Handle member 50 is segmented by cutouts such as cutout 63 to form segments 59 and 61, for example. First end 55 and second end 57, function similarly to that which is described in FIG. 1. Handle portion 53 is squeezed against the spring force of molded plastic living spring 65 so that second end 57 may be inserted into female fittage 61 of brush member 60. Upon release, recesses 67 and 69 fit into protrusions 63 and 65 so as to secure the brush member 60 until used. Thereafter, a simple squeeze of handle member 50 will release brush member 60 for instant, hands-free disposal.

[0031] In any of the above or below embodiments, the male and female fittages may be reversed so that the brush member fits into the handle member. In some embodiments, the brush member may be biodegradable, as, in the case of biodegradable plastics and or cellulosic or other degradable materials.

[0032] FIGS. 3,4,5, and 6 show views of various brushes which have a variety of possible remotely located lock operating mechanisms and different types of brushes. With respect to all of these figures, identical parts are identically numbered and are discussed only once in detail.

[0033]FIG. 3 shows a present invention cleaning brush having a handle member 70 and a brush member 73. There is a first end 75 and a second end 71 of handle member 70, with first end 75 terminating a handle, and including slide button 95. Second end 71 includes protrusions 77 and 79, which fit into recesses 93 and 97 of female fittage 91 of brush member 73 when the handle member 70 and the brush member 73 are connected.

[0034] When slide button 95 is moved upwardly, rod 81 and fins 83 and 85 also move upwardly such that fins 83 and 85 ride up stationary ramps 87 and 89 so as to be squeezed together and so as to pull protrusions 77 and 79 away from recesses 93 and 97, rendering brush member 73 free to drop away from handle member 70.

[0035] Brush member 73 has a bristled brush base 101, as shown. Alternatively, the brush member could be a spherical, elliptical, ovate, or other shaped structure formed of bristles, strands, cloth, sponge, or any other cleaning structure.

[0036] In FIG. 4, brush member 73 is identical to that shown in FIG. 3 and handle member 100 is similar to handle member 70 of FIG. 3, except that a wheel or dial replaces the button and appropriate internal modification has been made. Specifically, first end 105 of handle member 100 has a rotating dial 109 which is internally threaded and causes the threaded section 113 and rod 111 to rise or lower in response to rotating. This permits hand-free removal of brush member 73, as desired.

[0037]FIG. 5 shows a device similar to FIGS. 3 and 4, except that brush member 78 includes a sponge 107 and handle member 110 has a pull 119 at first end 115 of handle member 110 to move rod 117 upwardly to withdraw protrusions 77 and 79 from recesses 93 and 97. Likewise, FIG. 6 is also similar except that first end 121 has a trigger 125 for upward movement of rod 127 to effect activation of the unlocking feature. Additionally, brush member 130 has a hollow center 131 and a donut-shaped configuration with bristles, such as bristle 131.
